BALANCE-VALVE.

SPECIFICATION forming part of Letters Patent No. 352,801, dated November16, 1886.

Application filed August 18, 1886. Serial No. 211,205. (No model.)

To aZZ whom it may concern:

Be it known that I, ANDREW BEOKERT, a citizen of the United States,residing at Baltimore, in the State of Maryland, haveinvented certainnew and useful Improvements in Balance-Valves; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the .art to I which itappertains to make and use the same.

My invention relates to that form of valve which is shown in my formerpatent granted the 8th day of September, 1885; and its object is toprotect the springs which force the rings against the top plate of thesteam-chest from the action of the'steaml To accomplish this the springsare inclosed in a steam-tight compartment below the balance-plate, andpins resting upon the springs are projected through the openings formedin the bottom of the balance-ring recess for the purpose of supportingthe latter in the same substantial manner as if the rings were restingon the springs shown in the patent aforementioned. By these means thesprings are fully protected from the action of the steam and water, anda better valve is produced.

The nature of the invention therefore consists of constructions andcombinations, all as will hereinafter be described in the specification,and particularly pointed out in the claims, reference being had to theaccompanying drawings.

Figure 1 represents a top plan with one of the rings removed; Fig. 2, abottom plan of the balance-plate; Fig. 3, a section in line 00 m, Fig.1; Fig. 4, a perspective of a ring, and Fig. 5 a perspective of thespring.

The valve A, proper, may be constructed in any of the ordinary ways, andit will therefore not be necessary to show or describe the several partsthereof, as they are well known.

or the bottom of the balanceplate. In the present instance the underside of thebalanceplate is provided with long recesses a (which may beeither countersunk transversely or longitudinally, those shown, however,being transverse to the plate) for the springs, which may be ofelliptical form. At each end of the recesses 0. is drilled an opening, afor pins a which rest uponthe ends ofthe springs and project into thebalance-ring recess a, to support the balance-ring above the bottom ofthe latter, so that steam entering through the openings a of theoverhanging part of the an-' nular plate will have full play. Ifdesired, the under side of the plate may be provided with studs a to fitin corresponding studopenings, a, in the top of the valve, to assist thescrew-bolts a" in holding the balance-plate in place. By thisconstruction I am enabled to completely cover and protect the springsfrom the action of the steam and to add to the efficiency of the valvewhen in operationl What I claim as new is- 1. In a balance-valve, thecombination of a valve, a balance-plate secured to the valve and havinga balance-ring recess in the top and openings a the balance-ring, thesprings located between the valves and the balanceplate, and pinspassing through openings a .and interposed between the ring and springs,substantially as described.

2. In a balance-valve, the combination of a valve, a balance-plateoverhanging the body of the valve and provided with a balancering .saidopenings a and interposed between the springs and balance-ring,substantially as de- 3. In a balance-valve, the combination of a 5valve, 2. balance-plate secu red to the valve and having a balance-ringrecess, openings at and recesses on the under side, the balance-ring,the springs located in said recesses, and the. pins in said openings 0.and interposed between the springs and balance-rin s, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.
